All the files listed have very little value that's why there listed. There
is no way to determine the value of pantones colors listed in any of the
downloads and to use any of the files to compare rips and printers would be
a joke.
The Charts are all process equivalents not Pantone "Spot" Colors. When a
customer specifies a Pantone color he wants that color, he may get stuck
with the process equivalent unless he willing to pay.
And as for "process equivalents/simulations" under what criteria? Lowest
Delta E, maintaining hue etc.. No its what Pantone as randomly chosen at a
given moment in time.
Tell me what the color value is for Pantone XXX is. Say Pantone 192
You must have either the Lab value or an RGB value / and the RGB Color Space
neither of which Pantone will tell you. Yes, they also have RGB equivalents
in there swatch books except they won't define the RGB color space. If you
present the values in CMYK with a defined color space, I have a better
chance of randomly guess a more accurate color mix depending on what
criteria is used for comparison.
Pantone colors are Pantone colors and we use the process equivalents when a
device can't reproduce a high enough gamut to contain the true Pantone
Color. Even though Pantone will disagree and say that's why we have the
other books. You will very seldom see a customer create a file or specific
the correct process equivalent when dealing with Pantones ,I'm spoiled
because I can print all the Pantones Spot colors 3 percent more accurate
than Pantones own swatch books (legally signed off by them).
Pantone will never disclose any color values that could be used to do any
scientific color calculations to an average user........... Joe6Pack .."I
have a spectrophotometer, what should it read when I measure a patch that
was supposed to be Pantone 192 from CorelDraw/Illustrator. " Was that the
2002 version or the corrupt table version....
